鵬輝能源(300438.SZ):獲得專利證書 涉及鋰硫電池隔膜及其製備方法、鋰硫電池及其製備方法
格隆匯 07-01 18:19

格隆匯7月1日丨鵬輝能源(300438.SZ)公佈,公司及全資子公司近日收到國家知識產權局頒發的發明專利證書和外觀設計專利證書,其中,發明專利為鋰硫電池隔膜及其制備方法、鋰硫電池及其制備方法;外觀設計專利為儲能(便式)。

鋰硫電池隔膜及其制備方法、鋰硫電池及其制備方法,該發明提供了一種鋰硫電池隔膜及其製備方法、鋰硫電池及其製備方法,涉及隔膜技術領域,所述鋰硫電池隔膜包括支撐膜,所述支撐膜上覆合有摻氮碳吸導電塗層,所述鋰硫電池隔膜的製備方法包括如下步驟:將摻氮碳吸附電塗層塗覆於支撐膜上,幹燥後,得到鋰硫電池隔膜,緩解了傳統的隔膜對於多硫離子基本上是沒有阻擋作用,無法阻擋多硫化物溶出和穿梭現象的技術問題,通過在支撐膜上覆合有摻氮碳吸附導電塗層,使得多硫化物能夠被吸附在隔膜上,進行強導電性轉化,抑制多硫化物的“穿梭效應”,並降低界面反應阻力,有效回收正極與隔膜界面處的溶出硫,提高正極活性物質利用率,限制多硫化物的跨膜擴散,從而提高鋰硫電池的循環性能。

上述專利的取得和應用對公司目前的經營業績不會產生重大影響,有利於公司進一步完善知識產權保護體系,增強公司核心競爭力。
